Wilbers forkfedern for BMW K 75 RT 83-91

Product Details

Wilbers fork spring set, progressive, for BMW K 75 RT, Type BMW 75, model year 83-91 (please order forkoil separately), with ABE according to application list

General Description

Depending on the application, Wilbers offers progressive or linear fork springs, manufactured from the best and highest quality chrome-silicon steel. For touring and sport touring, we generally recommend a progressive fork spring to optimise response and, on the other hand, increase bottoming-out reserves. Crucially important is the combination of the "Zero Friction" fork springs with the specially developed Wilbers forkoil, as well as observing the correct air chamber for the respective vehicle. If desired, individual tuning can be achieved in special cases by changing the air chamber. For motorsport applications, we recommend the very light linear chrome-silicon fork springs from Wilbers, which were co-developed by the motorsport team.

"ZERO friction" friction reduction through vibratory finishing:
During vibratory finishing, the workpieces to be processed, such as Wilbers fork springs, are placed together with an abrasive media specifically designed for this purpose in a vibrating container, known as a trough vibrator.
The vibrations of the container create a relative movement between the workpiece and the abrasive media, leading to a smoothing of the component surface through constant rubbing. At the end of the process, a fine, shiny surface is achieved.
For Wilbers fork springs, this reduction in surface roughness means a minimisation of friction = ZERO friction.

Each fork spring set includes a recommendation for the viscosity of the forkoil and the height of the air chamber in the fork. These values have been determined by experienced Wilbers technicians and ensure optimum riding comfort and feedback at the handlebar.

Note: please order the forkoil separately.
